Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet ﷺ used to say, "If you have intercourse with your wife and then wish to go to sleep before doing ghusl, do not sleep until you have done wudu as for prayer."  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا كَانَتْ تَقُولُ إِذَا أَصَابَ أَحَدُكُمُ الْمَرْأَةَ ثُمَّ أَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ فَلاَ يَنَمْ حَتَّى يَتَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ  

I asked the Messenger of Allah ﷺ : O Messenger of Allah ﷺ, if one of us wants to sleep before doing ghusl when he is junub, what should he do? He said: ʿLet him do wudoo’ as for prayer, then sleep.”  

سَأَلْتُ رَسُولَ اللهِ ﷺ قُلْتُ يَا رَسُولَ اللهِ أَحَدُنَا إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ كَيْفَ يَصْنَعُ قَبْلَ أَنْ يَغْتَسِلَ؟ قَالَ يَتَوَضَّأُ وُضُوءَهُ لِلصَّلاةِ ثُمَّ يَنَامُ  

I asked the Messenger of Allah ﷺ what one of us should do if he becomes junub then wants to sleep before doing ghusl. The Messenger of Allah ﷺ said: “Let him do wudoo' as for prayer, then he may go to sleep.ʿ  

سَأَلْتُ رَسُولَ اللهِ ﷺ كَيْفَ يَصْنَعُ أَحَدُنَا إِذَا هُوَ أَجْنَبَ ثُمَّ أَرَادَ أَنْ يَنَامَ قَبْلَ أَنْ يَغْتَسِلَ؟ قَالَ فَقَالَ رَسُولُ اللهِ ﷺ لِيَتَوَضَّأْ وُضُوءَهُ لِلصَّلاةِ ثُمَّ لِيَنَمْ  

"If the Messenger of Allah ﷺ wanted to sleep while he was Junub, he would perform Wudu', and if he wanted to eat or drink," she said: "he would wash his hands and then eat or drink." (Using translation from Nasāʾī 257)   

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ كَانَ رَسُولُ اللهِ ﷺ إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ تَوَضَّأَ وُضُوءَهُ لِلصَّلَاةِ وَإِذَا أَرَادَ أَنْ يَأْكُلَ وَيَشْرَبَ قَالَتْ يَغْسِلُ يَدَيْهِ ثُمَّ يَأْكُلُ وَيَشْرَبُ  

[Machine] I asked Aisha, "How did the Messenger of Allah ﷺ act when he wanted to sleep while in a state of sexual impurity?" She said, "He would perform ablution as he does for prayer, then he would sleep."  

سَأَلْتُ عَائِشَةَ كَيْفَ كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ إِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ؟ فَقَالَتْ كَانَ «يَتَوَضَّأُ وُضُوءَهُ لِلصَّلَاةِ ثُمَّ يَنَامُ»  

"عَنْ عمر قالَ: سألتُ رسولَ اللَّه ﷺ كَيْفَ يصنعُ أحدُنَا إِذَا هُوَ أجْنَبَ، ثم أرادَ أن ينامَ قبل أن يَغْتَسِل؟ فَقَالَ: لِيتَوَضَّأ وضوءَهُ للصَّلَاةِ، ثمَّ لِيَنَمْ".
